Chateau LTE12 RouterOSv7 beta6 LTE won't connect

Thu May 21, 2020 8:31 pm

Hi!

So, I am new to MikroTik. I am new to these forums. I am not a complete newcomer to networking due to my work.

After spending 6 hours troubleshooting with a colleague (who uses MikroTik at work and at home) we are stumped. The router will not connect properly to my carrier (Vodafone UK) and shows good signal before even putting the external antenna in (Which I am not doing until the base device works.)

I am using the same settings as my previous 4G router (and have tried multiple different suggestions).

We keep seeing -internal error on the LTE interface.

We are only getting Transmit on the LTE interface nothing back. We have tried manually configuring and quick setup (Which for a home router should work)

A little surprised that it shipped with a Beta OS and cannot go back to stable. I cannot find v7 Beta6 online.

Any help would be much appreciated.

What settings you have for the lte interface?
Look in the Cellular tab on the LTE interface to see in which lte band it connects and if is uses CA when connection is established when doing data-transfer.

Please activate lte logs at start.
/system logging add topics=lte

Next you can show us export from lte by:
/interface lte export

Hi to all guys,

I'm new to this forum. My MikroTik Chateau LTE interface has a similar behavior.
The router will not connect properly to my carrier, but i receive a "--connect failed" error instead "--internal error" message like @th2000125
Capture1.jpg
I have tried with two sims that work properly on other MikroTik 4G routers and the behavior is the same.
This is the LTE log at routerboard boot
Capture2.jpg
[admin@MikroTik] > /interface lte monitor lte

Don't pay attention to the connection parameters because I did the tests indoor without any external antennas in a poor signal zone.
The CA seems to work well (appear only for few seconds and disappear) but first i need to solve the LTE connection problem.

Now I'm doing some tests to try the software and firmware downgrade to the routeros version 7.0beta4.

If i need to upgrade again to 7.0beta6 , where i can find it?

Any help or advice is greatly appreciated.

Regards,
Mirko

YOU DO NOT DO DOWNGRADE because MikroTik not publish ROS7b6 jet, you should very stuff ask at support@mikrotik.com insted of forum because we not have documentation jet, this is beta device with beta software.

* try send at-chat command at+reset
* try send at-chat command from my post to Quactel modules here:viewtopic.php?f=3&t=150368#p787894 like

I sold a Chateau and when I installed the SIM it put it self in boot-loop with no return.. I had to do a netboot and downgrade it to B5. B6 is not public soo..
It has worked fine sins.

I've had a quick snoot around our test one this afternoon
It does seem like that the v7beta6 version it comes with is quite broken,

The way it's reacting is as if the LTE package isn't loaded onto the main system package (as they got merged into one some versions back)
Even changing the setting from Auto to Internal or External Ant (with an antenna attached once rebooted of-course) made no difference,

Checked via CLI by monitor lte 0 but nothing there either,
LTE Scan brought nothing -- now all 4 carriers I know I can access inside the building as we have 2 masts at either end of the Ind. Estate which I get belting signals inside (EE, O2, Voda & three)

Perhaps some of the other tests that people have tried were on other versions (like beta4) have been able to spark the modem card into life a bit but as quite rightly mentioned beta6 is not available so hesitant to change the software version at the mo to do any further testing,

Interesting,

booted it up today after the tests yesterday and it seems to be working.. which is rather odd,

Seems that in the tinkering with the /system > routerBOARD > modem and changing the mode from Auto to Serial and then back to Auto along with changing the Main and Diversity Antennas (cycling through Auto, Internal External) seems to have forced it to do something,
Its now showing selected antenna as Internal

It also seems to be reading the "usb" PCI card for the LTE cat12 module (EG12-EA)

So perhaps it needed a further reboot after its booted up (and loaded in default script) to get it running -- much like you would when firmware updating and then upgrading bootloader etc,

Only differences to the "default" config that I've added is adding in the APN for the carrier the sim is currently using in it..
Rather odd...
Still running v7.0beta6

Kev

### EDIT ##
Possible bug with Antenna selection -- despite adding external antenna and selecting from Auto to External for /system routerboard modem it seems to prefer the internal antenna and states it as being internal selected even tho external is selected in dropdown

auto | serial | Internal | External
must be finish with a RB reboot.

beta6 have got roblems with APN... when you use default one and change his value to other one then ROS can remember old one and still use it ?!.
At telit lm940 the at-chat not work.
Sometimes change who not should do anythink with lte1 can do reconnection...
just beta system.

About Antennas config, read a this uldis answer, full post is very interesting and short :)

I would like to echo the last post - reboot after setting external antennas seems to work here. I have setup APNs for my providers and tested both with their separate different SIM cards and had no problem with this on my Chateau LTE12.

The thing that does not work that I really need is passthrough support. It is not supported in beta 6 on this device, contacted support and they have confirmed this but they did also say it will be supported and might be in the next beta.

Hi,
I have quite the same issue here (in France) tested with 2 different seems and always connect failed, we did try to create APN / Reset etc. and it's the same.
/interface lte apn add apn=free use-network-apn=no
/interface lte set lte1 apn-profiles=free
So trying to reach support from email, the main dif between one Chateau that works it's the difference on firmware on Quectel :
EG12EAPAR01A05M4G -> Working
EG12EAPAR01A04M4G -> Not working
Note the diff between A05 and A04 !

Is there the issue ?
Thanks.

EDIT : upgrading the LTE firmware did the trick :)

interface lte firmware-upgrade lte1 upgrade=yes

It changes to A06 and now no connect error, we can try more now :)

upgrading the LTE firmware did the trick :)
+2 other examples I have, I can confirm that it's good to do firmware-upgrade.

Yes :)
Ok for now the speed is not the same as other brand, not sure why :(
3CA can't keep up here on 4G French provider "FREE"

When disable LTE and re-enable 3CA are working and after few minutes it goes to 2CA (same WAN IP/same PCC) and/or 1CA right after !!!! it happens also on Netgear but seems less faster than LTE12.

This is weird !

I'm just doing another test and only 5 minutes after enable/disable the LTE interface : 3CA goes to 1CA and can't be reallocated :(

For sure on French 4G FREE provider, the aggregation is activated dynamically when data download is trigger at certain level. Maybe it's the root of this issue ?
I don't know for elsewhere (other country, etc.) but maybe aggregation is always activated whenever data download is idle or used !

exacly.
With the same ISP the
  • R11e-LTE6 keep CA
  • EP06 display not CA or sometimes CA state=1 (not active but configured). When you use traffic then CA is activated.
It's like differ firmware at differ module have other behavior. This is the politics of ISP too and that's why it's hard to predict how you have that in your country.

Thanks for confirmation, I didn't know that :)

So something can be done ? by supplying log or whatever information to support ?

Maybe I should open an own thread for it :)
Btw, i have seen official Quectel EM12 firmware :
EM12GPAR01A17M4G
EM12GPAR01A19M4G_01.001.01.001

Currently it's A06 and like we know now, A04 was not good but A05 and A06 fix the connection issue. So maybe latest modem firmware handle CA better ?

EM12GPAR01A17M4G
EM12GPAR01A19M4G_01.001.01.001
EG12 have few version with differ FW. Thats why we have other numbers and EM12 have other numeration.
Please be notive that xxAbb, it;s like:
xx main version
bb sub version
e.g. means, 01A08 is older then 02A01 who is the new one.

Mine is connecting on Voda in the UK, showing good signal and getting an IP address from Voda but not passing data to Chatau Wi-Fi or LAN firmware 7.b8.
Where do I find the modem firmware to update it?

Thanks

You need to have internet on LTE12 and execute those command :

Check the latest version available:
/interface lte firmware-upgrade lte1
and to upgrade:
/interface lte firmware upgrade lte1 upgrade=yes

Like I wasn't able to use LTE connection, I have set up WAN from Ethernet port1 to get internet on LTE12 and then apply above command.
And it updates from A04 to A06, be sure to not power off the router, it takes around 5 minutes to do it (after download is related to your internet connection) :)

Hey running right now into the CA issue and when performing LTE scan, it didn't find other band (I'm thinking it can be root of cause) :

/interface/lte/cell-monitor lte1
Columns: PHY-CELLID, BAND, EARFCN, RSRP, RSRQ, RSSI, AGE
PHY BA EARF RSRP RSRQ RSSI AG
186 B7 3350 -93dBm -20dB -63dBm 2s
187 B7 3350 -84dBm -10dB -52dBm 2s
-- [Q quit|D dump|C-z pause]

It only find B7 and no other band, so if it's really the issue, it can explain why it can doing CA for other band ?

Also I can confirm that other bands are available (from my phone with same operator) :)

Hi @SiB :)
Ok, thanks again for this information.

So we are agree in normal use :
We should always get those line in idle
lte,async,raw lte1 sent AT+QCAINFO
lte,async,raw lte1 rcvd +QCAINFO: "pcc",3350,100,"LTE BAND 7",1,187,-85,-7,-58,23
lte,async,raw lte1 rcvd +QCAINFO: "scc",1675,75,"LTE BAND 3",1,187,-82,-7,-58,21
lte,async,raw lte1 rcvd DL
lte,async,raw lte1 rcvd +QCAINFO: "scc",9460,50,"LTE BAND 28",1,187,-72,-13,-43,23
And with load :
lte,async,raw lte1 sent AT+QCAINFO
lte,async,raw lte1 rcvd +QCAINFO: "pcc",3350,100,"LTE BAND 7",1,187,-84,-8,-55,20
lte,async,raw lte1 rcvd +QCAINFO: "scc",1675,75,"LTE BAND 3",2,187,-81,-12,-49,18
lte,async,raw lte1 rcvd DL
lte,async,raw lte1 rcvd +QCAINFO: "scc",9460,50,"LTE BAND 28",2,187,-71,-14,-39,17
Here, after a while I wasn't able to receive SCC info in log and when starting : /interface/lte/cell-monitor lte1
I'm getting only B7 (from different PCID, i.e 187 and 186) but no more B3 or B28 (B31 typo)
I'm sure this is the issue now (close to 99% lol)

@SiB,

You are right, just tested another ISO download with IDM (to get full bandwidth):
- B7 and B3 are detected but no B28 (first bug)
- On B3, the "scell_state" stay to 1 (second bug) instead of 2

Ofc, changing band or enable/disable LTE maybe it back to work !!!

Example done on terminal :
Set B3+B7:
/interface lte at-chat lte1 input="AT+QCFG=\"band\",0,44,1"
Set B3+B7+B28:
/interface lte at-chat lte1 input="AT+QCFG=\"band\",0,8000044,1"

1- So a workaround would be to create a script (but I'm not good at this) but it's a hack :
To analyze current detected BAND "neighbourcell" or another command to see if all is present example : B7 + B3 + B28 (B31 typo)
1.2- Start to download something (like 16 or 32Mb ISO)
1.3- Analyze if B7 + B3 + B28 is always present and analyse if "scell_state" of SCCx (SCC1 and SCC2) are set to 2, if yes :
1.3.1- Do nothing, all is right
1.3.2- Enable some commands like above (change BAND) to reset the connection quickly as possible

2- Another solution would be to perform some commands reset without losing current IP WAN connection, then if we can find some kind of command like this, we can run the script all 3 our 5 minutes but I fear this type of command doesn't exist !

@SiB,

- B7 and B3 are detected but no B28 (first bug)
Sebastii, I am also on FREE network, but using Quectel EP06 (with WAP-R ac). I had B28 enabled together with the other bands
B1/3/7/20. It gives very bad performance (it stucks pretty much on B28 only). I now do not use B28 at all (disabled it), and it gives me
best performance (mostly using B3/B7 as always).
On B28 I had 1-3Mbps, while on CA with the other bands I can go up to 35-50Mbps depending on orientation...

Maybe this is because B28 are base stations in different locations than the "old" B3/B7 ones , thus no CA possible with those?
And as they are fully owned by Free, they want you to be on those...?

Hi WeWiNet :P
B28 works correctly alone here (added recently in end April), so I think it's a different case but maybe not after all.
When I scan the network neighboor, I can see other B28 like other B7 and B3 but when 3CA works, it uses the same PCID so the same tower, the one at 1.3km.
Thanks.

Similar problem.
Getting 'connect failed' error message for lte interface. It started suddenly around 20 hours after installing latest firmware 7.12beta3 version.
I have tried:
Full reset
Power off/on via power cable.
Switching APN profiles, some of them showed "service not activated", which i never saw previously when it was working.
Enabling 3g, 4g, 5g separately.
With only 4g, 5g enabled it shows only MCS and a blank field. No data class, no signal stats.
With 3g it shows data class HSUPA and rssi..

Showed no available cells when looking via cell monitor.
Seems the only way some kind of connection to tower, is made is via 3g, but there isn't any internet connectivity.

Have you tried going back to stable? Was this working on another version? Were the modem firmware and RouterBoard firmware also upgraded?
